NASA's Jet Propulsion Laboratory News and Features 9 Jul 2019, 15:49 UTC With careful planning and dashes of creativity, engineers have been able to keep NASA's Voyager 1 and 2 spacecraft flying for nearly 42 years - longer than any other spacecraft in history. To ensure that these vintage robots continue to return the best science data possible from the frontiers of space, mission engineers are implementing a new plan to manage them. And that involves making difficult choices, particularly about instruments and thrusters.
National Radio Astronomy Observatory (NRAO) 9 Jul 2019, 12:58 UTC Astronomers using National Science Foundation (NSF) radio telescopes have demonstrated how a combination of gravitational-wave and radio observations, along with theoretical modeling, can turn the mergers of pairs of neutron stars into a “cosmic ruler” capable of measuring the expansion of the Universe and resolving an outstanding question over its rate.
United Kingdom Space Agency 8 Jul 2019, 15:45 UTC Satellites are essential to modern life due to their application in navigation, finance, telecoms and in monitoring weather, climate change and air pollution. However, the data they collect can be slow to download due to the volume of traffic, with users often having to download very large files they don’t need just to obtain specific elements.
NASA's Goddard Space Flight Center 5 Jul 2019, 14:37 UTC This NASA/ESA Hubble Space Telescope image shows bright, colorful pockets of star formation blooming like roses in a spiral galaxy named NGC 972.
NASA's Chandra X-ray Observatory 3 Jul 2019, 17:00 UTC Like whirlpools in the ocean, spinning black holes in space create a swirling torrent around them. However, black holes do not create eddies of wind or water. Rather, they generate disks of gas and dust heated to hundreds of millions of degrees that glow in X-ray light.
